# Assetto Corsa

## Connection Method

**Shared Memory** — DR Sim Manager reads telemetry directly from Assetto Corsa's shared memory interface at up to **200 Hz**. No setup or configuration is needed.

## Setup Steps

1. Launch **Assetto Corsa**.
2. In DR Sim Manager, select **Assetto Corsa** from the Source list.
3. Click **Start Motion**.
4. Enter a session — telemetry starts automatically.

No plugins, configuration files, or network settings are required.

## Available Telemetry

Assetto Corsa provides excellent telemetry data:

- **Orientation**: Pitch, Roll, Heading (Yaw)
- **Acceleration**: 3-axis G-forces (lateral, longitudinal, vertical)
- **Velocity**: Full 3-axis local velocity
- **Angular Velocity**: 3-axis rotation rates
- **Speed**: Vehicle speed
- **RPM**: Engine RPM
- **Gear**: Current gear (including reverse and neutral)
- **Suspension**: 4-wheel suspension travel
- **Vehicle Name**: Read from static session data
- **ABS**: Anti-lock braking system status

### Telemetry Quality: ★★★★★

Assetto Corsa's shared memory provides high-frequency, low-latency data that produces smooth and accurate motion.

## Recommended Starting Settings

- **Primary Cue Gain**: 70–100%
- **Smoothing**: Low to medium
- **Washout**: Medium

## Known Quirks

- **Packet deduplication**: DR Sim Manager skips processing when the packet ID hasn't changed, ensuring no redundant data is used.
- **Works with Content Manager**: If you launch AC via Content Manager, telemetry still works normally through shared memory.
- **Modded cars**: Telemetry works with any car, including modded vehicles. The vehicle name is read from the session data.

## Troubleshooting

### No telemetry data

- Ensure Assetto Corsa is running and you are in a driving session (not in menus).
- Close any other applications that might be reading AC's shared memory exclusively.
- Restart both Assetto Corsa and DR Sim Manager.

### Motion stops mid-session

- This can happen if Assetto Corsa is minimized or loses focus in some configurations. Keep the game window active.

### Wrong car name displayed

- The car name is read from AC's static session data. If it shows incorrectly, try restarting the session.
